AUTOMATIC GATE.

SPECIFICATION forming part of Letters Patent No. 795,162, dated July 18, 1905,

Application filed May 24, 1905. Serial No. 262,027.

To all whmn it 711/1 1 concern:

Be it known that 1, AUGUSTUS Non, aeitizen of the United States, residing at 3728 Yakima avenue, city of Tacoma, in the county of Pierce and State of Washington, have invented certain new and useful Improvements in Automatic Grates, of which the following is a specilication.

My invention pertains to driveway-gates designed to be opened and closed from vehicles.

The objects of my invention are, first, to provide a simple and economical method for constructing and operating automatic gates, and, second, to provide a mechanical means whereby a gate may be opened and closed with a positive and easy action. I attain these objects by means of the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a side view of my invention. Fig. 2 is a top view of same. Fig. 3 is an end view of same. Fig. 4 is an enlarged view of the operating-wheel, and Figs. 5 and 6 are enlarged views of the operating segmental gearwheel.

Similar letters refer to similar parts in the several views.

My invention comprises a sliding gate constructed in any suitable form and of any material commonly used in the construction of fences and gates. The gate is provided with suspending sheaves A, designed to travel on a suitable track B, consisting, preferably, of a hollow tube.-or a stiff bar of iron may be used. The gate being thus suspended on a track, as described, can be easily moved back and forth. The novelty of my invention consists in the means for moving the gate back and forth upon the track thus described. The mechanism consists of a wheel or pulley O, mounted upon a rigid post set beside the fence and gate. A taut wire or thin cable D,

by a segmental gear F.

mental gear 'F is provided with a long slot or slide-opening G, with a socket-like extension H at each end. (See Figs. 5 and 6.) In this slide G is inserted a suitable clevis-shaped lift 1, pivotally mounted on a lifting-bar J, the upper end of which is connected with the opening-levers K, designed to be operated from a vehicle. The lower end of bar J is provided with a crescent-shaped extension L, which causes the clevis I to become anchored within the socket-shaped extension H and insures a positive lift on each side of the crescent gear F. The operating-levers K are provided with a suitable counterweight M, which causes the handles to rise when released by the operator. This causes the clevis-lift l. to slip down to the lower end of the slidegroove G preparatory to reversing the position of crescent gear F. The gate is opened or closed by pulling downward on the leverarms K, which causes the crescent wheel to turn on its pivot and revolve the wheel O, which drives the gate in the direction desired.

Fig. 1 represents the gate as closed and the crescent gear in the position shown in Fi 5. By pulling down upon the lever the gate is thrown open to the position indicated by the broken line N, and the crescent gear F is thrown to the position shown in Fig. (3. When the lever-arm is released, the clevis-lift 1 slides down into the position shown in Fig. 6

and is ready to operate the mechanism to close the gate when the lever-arm K is again pulled downward.

By the means above described the gate may be opened and closed with ease.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. An automatic sliding gate, comprising a gate, a pulley, a cable passingaround the pulley and connected to opposite ends of the gate, a crescent-shaped gear operatively connected with the pulley, a lift slidably connected with said gear to engage opposite sides thereof alternately, and operating lever-arms with which said lift is connected, substantially as shown and described.

2. An automatic slldlng gate, comprising a gate, a pulley, a cable connecting the gate and pulley, a crescent gear operatively connected with the pulley, a sliding lift connected with said gear, and lever-arms provided with a suitable counterweight to lift the outer ends of the lever-arms, substantially as shown and described.

3. A sliding gate, comprising the gate, a pulley, a cable connecting the pulley and gate, a pinion connected with the pulley, a segmental gear engaging the pinion and formed With an elongated slot, a lifting-bar slidably connected with said gear and adapted to slide from one end to the other of the slot in the gear, operating-levers connected with said bar, and a weight connected with said levers for restoring the levers'to their normal position and sliding the bar from one end to the other of the slot in the gear, substantially as described.

4. A sliding gate comprising a gate, apulley, a cable connecting the pulley and gate, a pinion connected with the pulley, a segmental gear operatively connected with said pinion and formed with an elongated slot, a liftingbar, a clevis pivotally connected to said bar and slidable in said slot, levers connected with said bar, and a weight for restoring the levers to their normal position and sliding the bar 'from one end to the other of the slot in the tension projecting from opposite sides of the bar at one end thereof to anchor the clevis at either end of the slot of the segmental member, and operating-levers connected with said bar, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

AUGUSTUS NOE.
